Facebook itself has an interest in having great content so that its users keep coming back.

If leadership requires a fired-up sense of purpose and imagination, it also demands a profound connection to the society to be led.

And it seems to me important for a country, for a nation to certainly know about its glorious achievements but also to know where its ideals failed, in order to keep that from happening again.

My father told me, "Don't do anything that would bring shame to the family." I was always mindful of that. When I told him I wanted to pursue a career as an actor, my father said, "Look at what you see on television at the movies, is that what you want to be doing? Do you want to make a life out of that?" And I said, "Daddy, I'm going to change it".

I'm an anglophile. I visit England regularly, sometimes three or four times a year, at least once a year.

To me, the amazing thing is that so much that was science fiction back then, political fiction, today is reality. We have indeed a spacecraft called an international space station. And we have the diversity of this planet working on that ship, including Americans and Russians working side by side. I think the imagineers are the ones that set the goal. And the inventors and the technicians see that as a goal to work toward, or the political scientists and the diplomats. And eventually, that's arrived at.
